Python Package

If you are not using Python version 3.4 or above, recent version of pip will
only install version 0.23.x. This is because newer versions of this package are
not compatible with Python 2.7 or 3.3 and below.

Standalone

Crash is also available as a standalone executable that includes all the
necessary dependencies, and can be run as long as Python (>= 3.4) is available
on your system.
